GT14 water pump trouble

M E Race · Jul 7, 2013

Hello fellow Yanmar fans. I seem to have run into a water pump problem with my 89 GT14. Does anyone know where or if you can get a replacement pump or rebuild kit for it? It has the 2T75U-NP motor, which does not show up on any of the sites I have found so far. I found the tractor on a local swap shop for a VERY low price with only 1028 hours, 3pth, 48 inch belly mower, grader blade, and a steel yard trailer made with 1/4 plate. Thanks in advance for any help.

Send Hoye tractor an email or phone call. They will be able to help you. Many of the water pumps are applicable on more than one engine, so there may be a pump that fits and is readily available. If not, you can probably take it to a rebuilder.

Thinking this is the part number for what it's worth. 124976-42100 And the seal. 121450-42310

I'm pretty sure they are rebuildable.

Thanks for the help, Hoye had the seal and bearing to rebuild it. That was def a pita. Got it rebuilt and back on and now I'm getting oil and pressure in radiator. No water in oil crankcase, so I'm thinking head gasket. I really don't see that as being a fun project. Will update with progress.

someone correct me if I'm wrong,but I don't think you would be getting oil in the radiator from a blown HG. unless, there's oil on top of the piston. And, There shouldn't be oil on top of the piston unless, the engine needs new rings,etc,

Maybe it is diesel and just looks like oil.

Or, maybe even some carbon/soot

Good possibility it is diesel since engine is not low on oil. Would a bad injector seal allow diesel to enter coolant in head?
The worst part of it is that I have a 3 cyl yanmar/John deere engine hanging on the back boom lift and none of the parts are interchangeable. It came out of a gator that the state used at Grande Ilse state park. But being state workers didn't involve cleaning it after running in salt water. Body literally rusted off, leaving low hour drive train.
